To Failback (Move) to the original protected site, the VPG that is now protecting the virtual machines at the recovery site have to be configured, if reverse protection was not selected, and then a Delta Sync is performed with the disks at the original protected site. Once the VPG is in a protecting state the virtual machines can be moved back to the original protected site, as described in “Migrating a VPG to a Recovery Site”, on page 343.
